Career
During the years 1926 – 1930 he worked for the Rheinische Metallwarenund Maschinenfabrik (Rheinmetall) in Sömmerda, Germany, where he developed a complete punched card-based accounting system, which was never mass-produced. The prototype of that system is currently stored in the archives of the Vienna Technical Museum. In the spring of 1928, Rheinmetall created a subsidiary company that was assigned to develop new punched card-based machines.
In the fall of the same year, the subsidiary was bought by International Business Machines Corporation, thereby assuring its monopoly on the market.
Tauschek was awarded a five-year contract and sold 169 patents to International Business Machines Corporation in his lifetime. Gustav Tauschek died of an embolism on February 14, 1945 in a hospital in Zürich, Switzerland.
